ABSTRACTPI: Samson A. Jenekhe Institution: University of WashingtonProposal Number: 0437912Research: The performance of current polymer electronic devices, such as thin film transistors, photovoltaic cells, and photodetectors, is limited primarily by the low charge carrier mobilities of current materials. The overall goal of this research is to develop next generation high carrier mobility polymer and hybrid organic-inorganic semiconductors and explore their device applications in electronics. The research is based in part on the principal investigator's (PI's) recent discovery of high electron mobility in spin coated, nanocrystalline, thin films of a conjugated ladder polymer. The planned research will: (i) develop new ladder polymer semiconductors having field-effect mobility of electrons exceeding 1 cm2/Vs; (ii) synthesize and develop new organic-inorganic hybrid semiconductors with carrier mobility exceeding 10 cm2/Vs; (iii) establish the relationships between charge carrier mobility and molecular structure and solid state morphology of polymer and hybrid organic-inorganic semiconductors; and (iv) explore the new high mobility ladder polymer and organic-inorganic hybrid semiconductors in field-effect transistors and photovoltaic cells. Broader Impacts: Polymers having high electron mobility will be useful for developing all-plastic complementary integrated circuits for logic and memory functions and for improving the efficiency of plastic solar cells. These advances could have major impact in accelerating the emerging era of plastic electronics for applications in many areas of information technologies and in portable power sources. The PI has developed courses on organic electronics and electronic and optoelectronic polymers that have been taken by graduate students in many fields including chemical engineering, chemistry, materials science, electrical engineering, bioengineering, physics, mechanical engineering, and forestry. The PI mentors several female and African American junior faculty in science and engineering at the University of Washington and other institutions. He is a consultant to a small start-up company interested in commercializing plastic electronics..

摘要：Samson A. Jenekhe机构：华盛顿大学提案编号：0437912研究：当前聚合物电子器件的性能，如薄膜晶体管、光伏电池和光电探测器，主要受到当前材料的低电荷载流子迁移率的限制。 本研究的总体目标是开发下一代高载流子迁移率聚合物和杂化有机-无机半导体，并探索其在电子学中的器件应用。 这项研究部分是基于首席研究员（PI）最近发现的高电子迁移率的旋涂，纳米晶，共轭梯形聚合物薄膜。 计划中的研究将：（i）开发电子场效应迁移率超过1cm 2/Vs的新型梯形聚合物半导体;（ii）合成和开发载流子迁移率超过10cm 2/Vs的新型有机-无机杂化半导体;（iii）建立电荷载流子迁移率与聚合物和杂化有机-无机半导体的分子结构和固态形态之间的关系;以及（iv）探索场效应晶体管和光伏电池中的新型高迁移率梯形聚合物和有机-无机混合半导体。更广泛的影响：具有高电子迁移率的聚合物将可用于开发用于逻辑和存储功能的全塑料互补集成电路以及用于提高塑料太阳能电池的效率。 这些进步可能会产生重大影响，加速塑料电子产品在信息技术和便携式电源的许多领域的应用。 PI开发了有机电子和电子及光电聚合物课程，这些课程已被许多领域的研究生所采用，包括化学工程，化学，材料科学，电气工程，生物工程，物理，机械工程和林业。 PI指导华盛顿大学和其他机构的几名女性和非洲裔美国人的科学和工程初级教师。 他是一家小型初创公司的顾问，该公司对塑料电子产品的商业化感兴趣。
